title: Effervescent agents in the double contrast examination of the stomach.
abstract: The buffer capacities of the BaSO4, contrast media are poor. Yet the pH changes caused by effervescent agents or gastric contents are insignificant for mucosal adsorption. The increase of the viscosity and decrease of the density impair the results of the examination.
